Sheet resistance

Sheet resistance, often called sheet resistivity, is a measure of resistance of thin films that are nominally uniform in thickness. It is commonly used to characterize materials made by semiconductor doping, metal deposition, resistive paste printing, and glass coating. Examples of these processes are: doped semiconductor regions (e.g

Resistance-heated vaporization boats for the vacuum vaporization of metals, such as aluminum, chromium, copper or the like, are made by machining a boat cavity in at least one side of a graphite bar. The bar is totally encapsulated over its entire outer surface, including the boat cavity, with a continuous coating of pyrolytic boron nitride (PBN).

What Is Induction Melting How Does It Work?

Induction Melting aluminum in a graphite crucible for casting Induction melting provides hands-free heating that involves no operator skill for manufacturing, repeatable, dependable results, more efficient and cost effective then gas furnace, does not heat up the manufacturing area and increases production.

The partial oxidation of the ferromagnetic metal during the process and the magnetization direction may play an important role in the determination of the quality of the remanent states. The ferromagnetic metal nanowires encapsulated inside CNTs demonstrate very high potential in providing the required magnetic properties, low dimensionality, and small volume for future nanoscale devices.

TRISO particles are then encapsulated into cylindrical or spherical graphite pellets. TRISO fuel particles are designed not to crack due to the stresses from processes (such as differential thermal expansion or fission gas pressure) at temperatures up to 1600 C, and therefore can contain the fuel in the worst of accident scenarios in a properly designed reactor.
